Who’s not lusting for that hard-core six pack around your midsection? With bikini season looming closer, or upon us for those trading snow for surf this time of year, the last thing we want to do is bare all on the beach or in the hot tub with flab abs. But forget the endless crunches, full sit-ups, reverse sit-ups, stability ball crunches and more that you find yourself doing to prep. You can tame that tummy without needing to leave the mountain and skip a ski day. The trick? Moguls.
